  • Patent number: 7019772
    Abstract: To enable the use of a single use digital camera for acquiring, selecting and storing images, that allows a customer to submit the captured images for development from a convenient location, while also providing the ability to delete unwanted images, a method is disclosed in which a customer is provided a single use digital camera, which the customer uses for acquiring, selecting and storing data corresponding to digital images, the data corresponding to selected images is received from the customer after the storing of the data and the selecting of the images. The single use digital camera does not provide the customer the ability to retrieve the stored data in image form. A method which includes additional steps allows the removal of selected ones of the data from the digital camera thereby preparing the camera for re-use. A system that provides the ability to perform the steps of the method for use of a single use digital camera is also described.

  • Patent number: 6999114
    Abstract: An electronic camera utilizing a reflective flat panel display for printing and/or viewing images in disclosed herein. One such electronic camera comprises the following components: (a) an electronic image acquisition assembly for capturing an image and converting it into digital information; (b) a reflective liquid crystal microdisplay for producing a reflection image in response to said digital information; and (c) an optical system for directing the reflection image produced by the reflective liquid crystal microdisplay toward, and thereby imagewise exposing, photosensitive imaging film loaded in the camera. An advantage of employing a reflective flat panel display for exposing film in such an electronic camera is that the reflective flat panel display can be used also as a means for viewing or previewing digitally captured images.

  • Patent number: 6997532
    Abstract: The present invention is directed to a digital image printer which incorporates a jogging system for providing an inexpensive printer for improving color saturation when imaging from a digital display which has monochromatic pixels. The device includes a printer having a housing that encloses, in a common cavity thereof, an arrangement including a digital area array display, a plurality of lenses, and an image plane. The digital area array display, the plurality of lenses, and the image plane are spaced along an optical axis extending from the digital area array display through the plurality of lenses, and toward the image plane such that a digital image provided by the display can be brought into focus onto the imaging plane by the plurality of lenses. One of the plurality of lenses is a transposable lens, the transposable lens capable of being transposed out of the optical axis during the operation of the printer, to increase the perceived resolution of the digital image focused onto the imaging plane.

  • Patent number: 6999202
    Abstract: In one aspect of the present invention, a method is provided for producing a halftone of a source image. The halftone includes halftone pixels. The halftone pixels are suitable for containing halftone dots. The method selects glyphs corresponding to intensities of regions (e.g., pixels) in the source image. The glyphs contain one or more halftone dots. The method locates halftone dots within the halftone pixels such that for at least one pair of halftone dots contained within a pair of halftone pixels sharing a common boundary, the halftone dots in the pair of halftone pixels extend in opposite directions from the common boundary.

  • Patent number: 6994257
    Abstract: The present invention relates to encoding and decoding of information using materials that are capable of mildly absorbing radiation over a wide range of infrared wavelengths and substantially non-absorbing in the visible wavelengths. Examples of such encoding of information are bar codes and area markings. Information is encoded in markings on a base medium by depositing or intertexturing on the base medium a material where the surface dimensions, thickness and presence of the material contain the encoded information. The encoding, as disclosed in this invention, utilizes a lower cost, more stable material than a material that is capable of highly absorbing over a range of infrared wavelengths and substantially non-absorbing in the visible wavelengths. However, since the material used in this invention is mildly absorbing in the infrared range, the signal obtained by reflecting or transmitting infrared radiation from the markings will be less distinct.

  • Patent number: 6976084
    Abstract: Techniques are disclosed for coupling a printer to a communications network (such as the a Plain Old Telephone Service network), downloading printing information (such as a digital image) to the printer over the communications network, and using the printer to print output based on the printing information. A user may use the printer to connect to a printing server that serves the printing information. Prior to transmission of the printing information to the printer, the printing server may process the printing information to tailor the printing information based on the capabilities of the printer. The printing server may communicate with the printer using one or more printing protocols. The printer may be equipped with a controller for communicating according to the printing protocol. Downloads of printing information to the printer may be interrupted and subsequently resumed from the point of interruption.

  • Patent number: 6946232
    Abstract: An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type where the image-receiving element is designed to be removed, or “peeled-apart” from a photosensitive element following exposure and photographic processing. The present image-receiving element comprises, in sequence, a support, an image-receiving layer and a strip-coat layer which serves to facilitate separation of the image-receiving element from the photosensitive element after photographic processing. The strip-coat layer comprises an anion of poly(acrylic acid), or a salt thereof, complexed with a cationic quaternary salt. In a preferred embodiment, the strip coat layer may include an ethoxylated alcohol.

  • Patent number: 6906736
    Abstract: A technique for optimizing or enhancing color images. Embodiments are disclosed for creating an enhanced color image, including the enhancement of perceived color uniformity. In a “dot-on-dot” registration scheme for producing color images, the dots need to be precisely superimposed on each other to provide optimum or enhanced images. The dot-on-dot registration produced by a single head thermal printer is generally acceptable, but a single head machine is very slow because multiple passes (reciprocation) are required to lay down multiple colors of dots. In a much faster multi-head or tandem thermal imaging system a serious problem of dot misalignment may cause moire patterns or other visual artifacts in the color images produced by dot patterns. A solution to this problem is disclosed herein which intentionally misregisters superimposed dots in a novel and particular manner to achieve image optimization.
